Author to whom correspondence should be addressed. Silicon (Si) is considered a promising anode active material to enhance energy density of lithium-ion batteries. Many studies have focused on new structures and the electrochemical performance, but only a few investigated the particulate properties in detail.
However, a wide commercial usage of Si as an anode material in lithium-ion batteries has not taken place yet. The reason for this is the volume change of up to 300% of the initial particle volume [ 4, 5 ], which may lead to particle breakage (pulverization) [ 6, 7 ], defects in the electrode structure and continuous SEI growth [ 8 ].
These majority silicon electrodes display remarkable cycle stability by reaching 1000 cycles with >80% capacity retention and exhibit little or no impedance gain or SEI growth. Changing the content and identity of aliovalent dopant atoms in silicon offers a new form of control over silicon active materials for lithium-ion battery technology.
A thin-film solid-state battery consisting of an amorphous Si negative electrode (NE) is studied, which exerts compressive stress on the SE, caused by the lithiation-induced expansion of the Si.
A far less explored but promising area of materials design is to change the composition of the silicon itself through alloying and doping. (27−29) More specifically, doping with elements that affect the electronic energy levels and surface chemistry. Silicon, doped with aliovalent elements, is the lynchpin of the modern electronics industry.
Figure 1 shows the ever-increasing number of published research articles with the topic on solid-state batteries (SSBs), in which almost an exponential growth is illustrated in yearly columns. In comparison to 255 articles in 2012, the number of articles has expanded by 10 times to 2581 in 2022.

There are three categories of negative electrode materials for lithium-ion batteries: intercalation materials, conversion materials, and alloys.1–3 Among these, alloys emerge as a promising option due to their higher Li storage capacity induced by al-loyingreactions.4,5 Silicon,as one of these alloys,has garnered attention as a prom-
Some call this new battery type silicon-carbon composite anode battery or silicon-carbon battery. Some also call it lithium-silicon battery. The terminologies are still evolving. But it is the most prevalent type of silicon battery technology around today in 2024 and the only one in use commercially (to the best of my knowledge).
The primary focus of this article centers on exploring the fundamental principles regarding how electrochemical interface reactions are locally coupled with mechanical and transport properties impacting battery performance, giving opportunities to design electrolyte and interface coating materials for advanced solid-state batteries.
However, there are some challenges before the practical application of silicon-based anodes. During the lithiation process, the silicon material undergoes a huge volume expansion (∼400%), leading to its cracking, pulverization, and falling off from the current collector, which significantly reduce its electrochemical performance (Fig. 1) [24], [25], [26].
